Greenhouse selenium-enriched grape planting method for double ripening and abundant production

Abstract

The invention belongs to the technical field of grape cultivation, and specifically relates to a double-cropping high-yield planting method for greenhouse selenium-rich grape. The double-cropping high-yield planting method comprises the following steps: soil preparation in a greenhouse and fertilization; ditching and planting preparation; seedling planting and soil compacting; watering, soil covering and film mulching; bud selection and shed building; bud picking and branch binding; fertilization and watering; fungicide spraying; shed-film removal; pruning in the period of dormancy; temperature increasing, dormancy breaking and watering; fertilization and temperature control; bud picking and long-tendril nipping; temperature control in flower season; fertilization and sterilization; management in the young fruit period and the fruit growth period; fruit picking; restoration of tree vigor; pruning and renewing; pinching and differentiation inducing; management in the second-cropping fruit and branch growth period; temperature control in the flower season; fertilization and sterilization; management in the young fruit period and the fruit growth period; management in the fruit maturation period; and renewing and circulation. The invention has the following beneficial effects: double-cropping maturation is realized, so the yield is improved; selenium is rich, and the quality is good; health and no pollution are achieved; the cost is low; labor is saved; and economic benefits are high.

Description

technical field [0001] The invention belongs to the technical field of viticulture, and in particular relates to a method for planting selenium-enriched grapes in a greenhouse that is double-ripe and rich in a year. Background technique [0002] Grape is one of the main cultivated fruit trees in China, and has a cultivation history of more than 2,000 years in my country. Its fruit has high nutritional value, and the sugar content of fresh fruit is 10-30%. It contains a variety of minerals and vitamins beneficial to the human body, and is very popular among people. [0003] The cultivation of grapes in greenhouses also has decades of development. Whether it is open-air or greenhouse cultivation, most of them adopt the original planting mode: one year of planting, two years of strong seedlings, three years of high yield, and seven or eight years later, it will enter a recession period. , mature one season a year. This is still the case in the greenhouse, and it matures year ...

Problems solved by technology

This not only wastes the effective resources of greenhouse facilities and land, but also cannot achieve better economic benefits

In addition, the ripening period of grapes is relatively concentrated, resulting in oversupply in the peak production season and short supply in the off-season, especially during the winter and Spring Festival, when there are no fresh selenium-enriched grapes to pick, seriously affecting economic benefits
